Description

本発明は、不等辺不等厚山形鋼などの形鋼に発生した耳状突起物を除去する方法に関する。   The present invention relates to a method for removing ear-shaped protrusions generated in a shape steel such as an unequal side unequal thick angle steel.

一般に、船体の防撓材などに使用される不等辺不等厚山形鋼は横断面が矩形の山形鋼素材を熱間圧延して製造されるため、山形鋼素材を熱間圧延するときに素材の噛み出しが圧延ロール間に発生すると、図１１に示すような耳状突起物２が不等辺不等厚山形鋼１の短辺部１ａや長辺部１ｂの端部に発生する。そして、耳状突起物２が不等辺不等厚山形鋼１の短辺部１ａや長辺部１ｂの端部に発生すると、不等辺不等厚山形鋼１を構造物として用いる際に、この端部を他の部材と溶接する場合には、溶け込み不足などの溶接欠陥が発生したり、また塗装を行う場合には塗装むらが発生したりすることがあるため、不等辺不等厚山形鋼などの形鋼に発生した耳状突起物２を取り除く必要がある。   In general, non-equal unequal thick angle steel used for ship stiffeners, etc. is manufactured by hot rolling a square steel material with a rectangular cross section. 11 is generated between the rolling rolls, an ear-shaped protrusion 2 as shown in FIG. 11 is generated at the ends of the short side 1a and the long side 1b of the unequal side unequal thickness steel. And when the ear-shaped projection 2 is generated at the end of the short side 1a or the long side 1b of the unequal side unequal thickness chevron, when using the unequal side unequal thickness chevron 1 as a structure, When welding the end part with other members, welding defects such as insufficient penetration may occur, and when coating is performed, uneven coating may occur. It is necessary to remove the lug 2 generated in the shape steel.

不等辺不等厚山形鋼などの形鋼に発生した耳状突起物を除去する方法としては、周面部にワイヤが植設されたワイヤブラシを耳状突起物に接触させ、このワイヤブラシを回転させて耳状突起物を削り落す方法が知られている（特許文献１参照）。
実開昭６２−１３４６５３号公報 As a method of removing the ear-shaped projections generated in the shape steel such as the unequal-sided unequal thickness steel, the wire brush with the wire implanted on the peripheral surface is brought into contact with the ear-shaped projections and the wire brush is rotated. A method of scraping off the ear-like projections is known (see Patent Document 1).
Japanese Utility Model Publication No. 62-134653

しかしながら、特許文献１に開示された技術では、形鋼に発生した耳状突起物の高さが形鋼の長手方向に一定の場合には耳状突起物が発生した形鋼の表面を平滑に研削することが可能であるが、耳状突起物の高さが形鋼の長手方向に不定の場合や形鋼に曲がりや反りなどがある場合には耳状突起物が形鋼に残存したり、耳状突起物が発生した形鋼の表面を削り過ぎたりすることがあった。   However, in the technique disclosed in Patent Document 1, when the height of the ear protrusions generated in the shape steel is constant in the longitudinal direction of the shape steel, the surface of the shape steel in which the ear protrusions are generated is smoothed. It is possible to grind, but when the height of the ear projection is indefinite in the longitudinal direction of the shape steel, or when the shape steel is bent or warped, the ear projection remains on the shape steel. In some cases, the surface of the shape steel on which the ear-like protrusions were generated was excessively shaved.

本発明は上述した点に着目してなされたものであり、その目的は、形鋼に発生した耳状突起物を確実に除去することのできる形鋼の耳状突起物除去方法を提供することにある。   The present invention has been made paying attention to the above-described points, and an object thereof is to provide a method for removing an ear-shaped projection of a shape steel that can reliably remove the ear-shaped projection generated in the shape steel. It is in.

上記課題を解決するために、請求項１記載の発明に係る形鋼の耳状突起物除去方法は、熱間圧延するときの素材の圧延ロール間への噛み出しにより形鋼の端部に発生した耳状突起物を、研削加工ヘッドを有する耳状突起物除去装置を用いて除去するに際して、前記端部の位置を端部位置検出器により検出し、この端部位置検出器で検出された端部位置に基づいて前記研削加工ヘッドの位置を制御しながら前記耳状突起物を除去するようにしたことを特徴とする。 In order to solve the above-mentioned problem, the method for removing the lug-like projections of the shape steel according to the invention described in claim 1 is generated at the end of the shape steel due to the biting of the material between the rolling rolls during hot rolling. When the ear- shaped protrusions are removed using an ear-shaped protrusion removing device having a grinding head, the position of the end is detected by an end position detector, which is detected by the end position detector. The ear protrusions are removed while controlling the position of the grinding head based on the end position.

請求項１記載の発明に係る形鋼の耳状突起物除去方法では、耳状突起物の高さに応じて研削加工ヘッドの位置が耳状突起物の高さ方向に変位するため、形鋼に発生した耳状突起物を確実に除去することができる。 In the method for removing the shape protrusions of the shape steel according to the first aspect of the invention, the position of the grinding head is displaced in the height direction of the shape of the protrusions according to the height of the protrusions. It is possible to reliably remove the ear-like protrusions generated in the step.

以下、本発明の実施の形態を図面に基づいて説明する。図１は第１の発明に係る形鋼の耳状突起物除去方法によって耳状突起物を除去する場合に用いられる耳状突起物除去装置の一例を示す図であり、同図に示されるように、不図示の仕上圧延機、場合によっては仕上圧延後に矯正機を通過した不等辺不等厚山形鋼１を複数の搬送ローラ３により矢印方向に搬送する搬送ラインの左右両側には、不等辺不等厚山形鋼１をガイドする複数の開度変更可能なローラガイド４が設けられている。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a view showing an example of an ear-like protrusion removing device used when removing an ear-like protrusion by the method for removing an ear-like protrusion of a shape steel according to the first invention, and as shown in FIG. In addition, a non-illustrated finish rolling mill, and in some cases, unequal sides on the left and right sides of a conveyance line that conveys the unequal side unequal thick angle steel 1 that has passed through the straightening machine after finish rolling in the direction of the arrow by a plurality of conveyance rollers 3 A plurality of roller guides 4 capable of changing the opening are provided for guiding the unequal thick angle steel 1.

図２は図１のII−II断面を示す図であり、同図に示されるように、搬送ローラ３により搬送される不等辺不等厚山形鋼１の上方には、不等辺不等厚山形鋼１の短辺部１ａの端部に発生した耳状突起物２を除去する耳状突起物除去装置５が設けられている。
耳状突起物除去装置５は円筒状の研削加工ヘッド５ａを有しており、この研削加工ヘッド５ａを駆動モータ５ｂにより回転駆動して不等辺不等厚山形鋼１の短辺部１ａに発生した耳状突起物２を除去するように構成されている。また、耳状突起物除去装置５は駆動モータ５ｂを耳状突起物２の高さ方向に進退駆動するアクチュエータ５ｃを有しており、このアクチュエータ５ｃには、研削加工ヘッド５ａの高さ位置を制御するコントローラ６から制御信号が供給されるようになっている。 FIG. 2 is a cross-sectional view taken along the line II-II in FIG. 1. As shown in FIG. 2, the unequal side unequal thickness chevron is disposed above the unequal side unequal thickness steel 1 conveyed by the transport roller 3. An ear projection removing device 5 for removing the ear projection 2 generated at the end of the short side 1a of the steel 1 is provided.
The ear-shaped protrusion removing device 5 has a cylindrical grinding head 5a, and this grinding head 5a is rotationally driven by a drive motor 5b and is generated in the short side portion 1a of the unequal side unequal thick angle steel 1. It is comprised so that the ear-shaped projection 2 which performed may be removed. Further, the ear projection removing device 5 has an actuator 5c that drives the drive motor 5b to move back and forth in the height direction of the ear projection 2, and the height position of the grinding head 5a is set in the actuator 5c. A control signal is supplied from the controller 6 to be controlled.

図３は図１のIII−III断面を示す図であり、同図に示されるように、搬送ローラ３により搬送される不等辺不等厚山形鋼１の上方には、耳状突起物除去装置５により除去される前の短辺部１ａの端部位置を検出する端部位置検出器７が設けられている。
端部位置検出器７は高さ検出用ローラ７ａを有しており、この高さ検出用ローラ７ａの周面部を短辺部１ａの先端部に上方から接触させて短辺部１ａの端部の高さを検出する構成となっている。また、端部位置検出器７は高さ検出用ローラ７ａの上下方向の変位を検出する変位センサ７ｂを有しており、この変位センサ７ｂで検出された高さ検出用ローラ７ａの変位は、短辺部１ａの端部の高さ情報としてコントローラ６に供給されるようになっている。 FIG. 3 is a cross-sectional view taken along the line III-III of FIG. 1, and as shown in FIG. An end position detector 7 for detecting the end position of the short side portion 1a before being removed by 5 is provided.
The end position detector 7 has a height detection roller 7a, and the peripheral surface portion of the height detection roller 7a is brought into contact with the distal end portion of the short side portion 1a from above to end the short side portion 1a. The height is detected. The end position detector 7 has a displacement sensor 7b for detecting the vertical displacement of the height detection roller 7a. The displacement of the height detection roller 7a detected by the displacement sensor 7b is as follows. The information is supplied to the controller 6 as the height information of the end of the short side 1a.

このような構成において、不等辺不等厚山形鋼１の短辺部１ａに発生した耳状突起物２に耳状突起物除去装置５の研削加工ヘッド５ａを接触させて耳状突起物２を研削しているときに研削加工される前の短辺部１ａの端部の高さが変化すると、端部位置検出器７の高さ検出用ローラ７ａが高さ方向に変位する。そして、高さ検出用ローラ７ａが高さ方向に変位すると、高さ検出用ローラ７ａの変位量が端部位置検出器７の変位センサ７ｂによって検出される。   In such a configuration, the ear-shaped protrusion 2 is formed by bringing the grinding head 5a of the ear-shaped protrusion removing device 5 into contact with the ear-shaped protrusion 2 generated on the short side portion 1a of the unequal thickness uneven steel 1. When the height of the end of the short side 1a before grinding is changed during grinding, the height detecting roller 7a of the end position detector 7 is displaced in the height direction. When the height detection roller 7 a is displaced in the height direction, the displacement amount of the height detection roller 7 a is detected by the displacement sensor 7 b of the end position detector 7.

このようにして、高さ検出用ローラ７ａの変位量が変位センサ７ｂによって検出されると、変位センサ７ｂで検出された高さ検出用ローラ７ａの変位量が端部位置情報として変位センサ７ｂからコントローラ６に供給される。そして、高さ検出用ローラ７ａの変位量が端部位置情報として変位センサ７ｂからコントローラ６に供給されると、コントローラ６は、研削加工ヘッド５ａの研削加工位置を変更するヘッド位置変更信号を耳状突起物除去装置５のアクチュエータ５ｃに送出する。これにより、耳状突起物２の発生した部分が耳状突起物除去装置５の研削加工ヘッド５ａによって平滑に研削されるため、図１〜図３に示した実施の形態では、不等辺不等厚山形鋼１に発生した耳状突起物２を確実に除去することができる。   Thus, when the displacement amount of the height detection roller 7a is detected by the displacement sensor 7b, the displacement amount of the height detection roller 7a detected by the displacement sensor 7b is detected from the displacement sensor 7b as end position information. It is supplied to the controller 6. When the displacement amount of the height detection roller 7a is supplied from the displacement sensor 7b to the controller 6 as end position information, the controller 6 receives a head position change signal for changing the grinding position of the grinding head 5a. It is sent to the actuator 5 c of the projection-like protrusion removing device 5. As a result, the portion where the ear-like protrusions 2 are generated is smoothly ground by the grinding head 5a of the ear-like protrusion removal device 5, so that in the embodiment shown in FIGS. The ear-shaped protrusion 2 generated in the thick steel 1 can be reliably removed.

以上説明した、実施形態においては、形鋼が上下方向に変形している場合に、形鋼の搬送に伴い、耳状突起物を除去すべき端部が上下方向に変位するので、端部位置検出器７では端部の上下方向位置を検出し、この検出結果にもとづきアクチュエータ５ｃは、研削加工ヘッド５ａの上下方向位置を変更するようにしているが、形鋼が左右方向への変形がある場合には、搬送に伴い端部は左右方向にも変位するので、端部の水平方向（左右方向）位置を検出する検出ローラを設けて、さらに、研削加工ヘッド５ａの水平方向位置を変更するアクチュエータを設けるようにしてもよい。   In the embodiment described above, when the shape steel is deformed in the vertical direction, the end portion where the ear-shaped protrusions are to be removed is displaced in the vertical direction as the shape steel is conveyed. The detector 7 detects the vertical position of the end, and the actuator 5c changes the vertical position of the grinding head 5a based on the detection result. However, the shape steel is deformed in the horizontal direction. In this case, since the end portion is also displaced in the left-right direction as it is conveyed, a detection roller for detecting the horizontal position (left-right direction) of the end portion is provided, and the horizontal position of the grinding head 5a is further changed. An actuator may be provided.

図４は、短辺部の水平方向位置についても検出できるようにした端部位置検出器７を示す図である。この例では、図３に示した検出器７に対して、高さ検出用ローラ７ａに加えて、水平位置検出用ローラ７ｃをさらに有しており、この水平位置検出用ローラ７ｃの周面部を短辺部１ａの先端部に水平方向（図３の例では右方向）から接触させて短辺部１ａの端部の水平方向の位置を検出する構成となっている。また、水平位置検出用ローラ７ｃの変位を検出する変位センサ７ｄを有しており、この変位センサ７ｄで検出された高さ検出用ローラ７ｃの変位についても、短辺部１ａの水平位置情報としてコントローラ６に供給されるようになっている。   FIG. 4 is a diagram showing the end position detector 7 that can detect the horizontal position of the short side portion. In this example, in addition to the height detection roller 7a, the detector 7 shown in FIG. 3 further includes a horizontal position detection roller 7c. The peripheral surface portion of the horizontal position detection roller 7c is The position of the end of the short side 1a in the horizontal direction is detected by contacting the tip of the short side 1a from the horizontal direction (right in the example of FIG. 3). Further, a displacement sensor 7d for detecting the displacement of the horizontal position detecting roller 7c is provided, and the displacement of the height detecting roller 7c detected by the displacement sensor 7d is also used as the horizontal position information of the short side portion 1a. It is supplied to the controller 6.

図５は、図２に示した耳状突起物除去装置５に対して、研削加工ヘッド５ａの水平方向位置を変更するアクチュエータ５ｄをさらに設けた例である。図５に示したように構成することで、研削加工ヘッド５ａを上下方向および水平方向のいずれにも短辺部１ａが変位した場合にも、研削加工ヘッド５ａを短辺部１ａの端部位置に追従させることができ、確実に耳状突起物を除去することができるようになる。   FIG. 5 is an example in which an actuator 5d for changing the horizontal position of the grinding head 5a is further provided to the ear projection removing device 5 shown in FIG. By configuring as shown in FIG. 5, even when the short side 1a is displaced both in the vertical direction and in the horizontal direction, the grinding head 5a is positioned at the end of the short side 1a. The ear-like projections can be surely removed.

図６は第１の発明に係る別の実施形態を示す図である。図６に示す実施形態では、略円柱状の研削加工ヘッド１５ａの底面部にて耳状突起物を研削する構成となっており、短辺部１ａの端部の斜め上方より研削加工ヘッド１５ａを押付ける構成となっている。
研削加工ヘッド１５ａは、駆動モータ１５ｂにより回転駆動される。駆動モータ１５ｂは、搬送ラインに対して固定位置に配置された支持部材（ヘッドホルダ）１５ｅに、搬送ラインに対して斜め上方から進退自在となるよう、支持部材（ヘッドホルダ）１５ｅから搬送ラインへ向けて斜め下方へ延びたスライド軸１５ｇにスライド可能に支持されている。さらに、支持部材１５ｅに加工ヘッドの進退用のアクチュエータとしてモータ１５ｃが固定配置されており、該モータ１５ｃにより回転駆動されるねじ軸１５ｆには、ナット部材１５ｄを介して駆動モータ１５ｂが取り付けられている。よって、モータ１５ｃによりねじ軸１５ｆを回転させることにより、加工ヘッド１５ａが搬送ラインに対して進退動作を行う。加工ヘッドの進退用のモータ１５ｃの制御はコントローラ６が行う。コントローラ６は、図４に示した端部位置検出器７から供給された、短辺部１ａの端部の位置情報に基づき、加工ヘッドの進退位置を決定し、加工ヘッドを決定した進退位置に合わせるようモータ１５ｃを駆動させる。 FIG. 6 is a diagram showing another embodiment according to the first invention. In the embodiment shown in FIG. 6, the ear-shaped protrusion is ground at the bottom surface of the substantially cylindrical grinding head 15 a, and the grinding head 15 a is inclined from above the end of the short side portion 1 a. It is configured to press.
The grinding head 15a is rotationally driven by a drive motor 15b. The drive motor 15b moves from the support member (head holder) 15e to the transport line so that the support member (head holder) 15e disposed at a fixed position with respect to the transport line can move forward and backward with respect to the transport line. It is slidably supported by a slide shaft 15g extending obliquely downward. Further, a motor 15c is fixedly disposed on the support member 15e as an actuator for advancing and retreating the machining head, and a drive motor 15b is attached to a screw shaft 15f that is rotationally driven by the motor 15c via a nut member 15d. Yes. Therefore, by rotating the screw shaft 15f by the motor 15c, the processing head 15a moves forward and backward with respect to the transport line. The controller 6 controls the motor 15c for advancing and retracting the machining head. The controller 6 determines the advancing / retreating position of the machining head based on the position information of the edge of the short side 1a supplied from the edge position detector 7 shown in FIG. The motor 15c is driven to match.

図中破線で示した短辺部１ａのように上下方向および水平方向のいずれにも短辺部１ａが変位した場合にも、研削加工ヘッド１５ａを短辺部１ａの端部位置に追従させることができ、確実に耳状突起物を除去することができるようになる。本実施形態の場合には、図５に示した実施形態に対してアクチュエータは１つにしても、短辺部１ａの上下方向および水平方向の変位に追従可能となる。但し、略円柱状の加工ヘッド１５ａの研削面（底面部）の大きさが小さいと、短辺部１ａの変位量が大きい場合に、耳状突起物が生ずる短辺部１ａの端部に加工ヘッドを接触させることができなくなるため、短辺部１ａの変位量の経験値から、どのような変位量の形鋼が搬送されてきても、加工ヘッド１５ａの研削面を短辺部１ａの端部に接触させることができるよう、加工ヘッド１５ａの大きさを決定しておけばよい。   Even when the short side 1a is displaced both vertically and horizontally like the short side 1a indicated by a broken line in the drawing, the grinding head 15a is caused to follow the end position of the short side 1a. Thus, the ear-like projections can be reliably removed. In the case of this embodiment, even if the number of actuators is one with respect to the embodiment shown in FIG. 5, it is possible to follow the vertical and horizontal displacements of the short side portion 1a. However, if the grinding surface (bottom surface portion) of the substantially cylindrical processing head 15a is small, the end of the short side portion 1a where the ear-shaped protrusions are formed when the displacement amount of the short side portion 1a is large is processed. Since the head cannot be brought into contact, the grinding surface of the machining head 15a is adjusted to the end of the short side 1a regardless of the amount of displacement of the shape steel from the empirical value of the amount of displacement of the short side 1a. What is necessary is just to determine the magnitude | size of the process head 15a so that it can contact a part.

図１〜図６に示した実施の形態では、短辺部１ａの端部位置を端部位置検出器７によって検出し、この端部位置検出器７で検出された短辺部１ａの端部位置に応じて研削加工ヘッドの位置を制御しながら耳状突起物２を削り落すようにしたが、例えば、図２に示す耳状突起物除去装置に対しては、図７に示すように、端部に接触する研削加工ヘッド５ａの接触圧を圧力センサ８で検出し、研削加工ヘッド５ａの接触圧が一定となるように研削加工ヘッド５ａの位置をコントローラ６で制御しながら耳状突起物２を削り落すようにしてもよい（第２の発明の実施形態）。   In the embodiment shown in FIGS. 1 to 6, the end position of the short side 1 a is detected by the end position detector 7 and the end of the short side 1 a detected by the end position detector 7. The ear projection 2 is scraped off while controlling the position of the grinding head according to the position. For example, for the ear projection removing apparatus shown in FIG. 2, as shown in FIG. The contact pressure of the grinding head 5a in contact with the end is detected by the pressure sensor 8, and the position of the grinding head 5a is controlled by the controller 6 so that the contact pressure of the grinding head 5a is constant. 2 may be scraped off (embodiment of the second invention).

また、図６に示す耳状突起物除去装置に対しては、端部に接触する研削加工ヘッド１５ａの接触圧を、例えば図８に示すように、ナット部材１５ｄと駆動モータ１５ｂとの間に配置したセンサ１８で検出し、研削加工ヘッド１５ａの接触圧が一定となるように研削加工ヘッド１５ａの位置をコントローラ６で制御しながら耳状突起物２を削り落すようにしてもよい（第２の発明の別の実施形態）。   For the ear projection removing device shown in FIG. 6, the contact pressure of the grinding head 15a that contacts the end is set between the nut member 15d and the drive motor 15b as shown in FIG. 8, for example. The ear-shaped protrusion 2 may be scraped off while the position of the grinding head 15a is controlled by the controller 6 so that the contact pressure of the grinding head 15a is constant, as detected by the arranged sensor 18. Another embodiment of the invention).

また、図２に示した耳状突起物除去装置に対して、図９に示すように、研削加工ヘッド５ａとこれを保持するヘッドホルダ５ｅとの間にバネ等の弾性体９を設け、この弾性体９の弾性力により研削加工ヘッド５ａの周面部を耳状突起物２の先端部に押し当てて耳状突起物２を削り落すようにしてもよい（第３の発明の実施形態）。
図６に示す耳状突起物除去装置に対しても同様に、図１０に示すように、研削加工ヘッド１５ａとこれを保持するヘッドホルダ１５ｅとの間にバネ等の弾性体９を設け、この弾性体９の弾性力により研削加工ヘッド１５ａの底面部を耳状突起物２の先端部に押し当てて耳状突起物２を削り落すようにしてもよい（第３の発明の別の実施形態）。この場合、図６に示したモータ（アクチュエータ）１５ｃは必要なく、また、ねじ軸１５ｆはスライド軸１５ｇと同様にしておけばよく、単に駆動モータ１５ｂとスライド軸とを、スライド可能に接続しておけばよい。 Further, as shown in FIG. 9, an elastic body 9 such as a spring is provided between the grinding head 5a and the head holder 5e holding the same, as shown in FIG. The peripheral surface of the grinding head 5a may be pressed against the tip of the ear-shaped protrusion 2 by the elastic force of the elastic body 9 to scrape off the ear-shaped protrusion 2 (Embodiment of the third invention).
Similarly, as shown in FIG. 10, an elastic body 9 such as a spring is provided between the grinding head 15a and the head holder 15e for holding the same, as shown in FIG. The bottom surface of the grinding head 15a may be pressed against the tip of the ear projection 2 by the elastic force of the elastic body 9 to scrape off the ear projection 2 (another embodiment of the third invention). ). In this case, the motor (actuator) 15c shown in FIG. 6 is not necessary, and the screw shaft 15f may be the same as the slide shaft 15g. The drive motor 15b and the slide shaft are simply connected so as to be slidable. Just keep it.

上述した各実施の形態では不等辺不等厚山形鋼１の短辺部１ａの端部に発生した耳状突起物２を除去する場合を例示したが、不等辺不等厚山形鋼１の長辺部１ｂの端部に発生した耳状突起物を除去する場合にも適用することが可能である。また、耳状突起物２が発生する形鋼として不等辺不等厚山形鋼１を例示したが、等辺等厚山形鋼などの形鋼に発生した耳状突起物についても確実に除去することができる。   In each of the above-described embodiments, the case where the ear-shaped protrusion 2 generated at the end of the short side 1a of the unequal side unequal thickness iron 1 is removed is illustrated. The present invention can also be applied to the case where the ear-shaped protrusions generated at the end of the side portion 1b are removed. Further, although the unequal side unequal thick angle steel 1 has been exemplified as the shape steel in which the ear-shaped protrusion 2 is generated, the ear-shaped protrusion generated in the shape steel such as the equal side thickness thick angle steel can be surely removed. it can.
